<p>In the meeting today we discussed adding a marker to traits to mark them object safe or not, e.g. <code>dyn trait Foo { }</code> - only this is object safe or <code>static trait Foo { }</code> - this trait is not object safe. Lots of questions about what the unmarked default should be, etc</p>

<p>I wanted to comment: we definitely* would* want at least a lint if an unmarked trait contains non-object safe items, because that would alert people when they make a breaking change by making a trait accidentally no longer object safe.</p>

<p><span class="user-mention" data-user-id="256759">@boats</span> I think you meant to post this in <a class="stream" data-stream-id="213817" href="/#narrow/stream/213817-t-lang">#t-lang</a>, not in wg-meta?</p>
